Marie France Roy is a professional snowboarder from Canada who cares deeply about the environment so she decided to experiment with building a tiny home using natural and reclaimed materials. The result is a spectacular organic-shaped cabin that she’s been living in for 4 years now.
It’s two-stories and measures approximately 400 square feet. The main floor is built with a wood frame and cob walls made of sand, clay, and straw. The second floor is built with reclaimed wood.

Her Magical 400-sq.-ft. Cob Cottage

When building with cob, it’s important to have a good roof to protect the walls from direct rain and snow, so Marie France has an overhanging roof on the top floor, and a second skirt roof around the porch.

The house is an irregular round shape, and it has a ton of light coming in from the secondhand windows, glass blocks and glass bottles that she incorporated into the walls. What you can’t see is that inside the walls she also put jars filled with garbage that couldn’t be recycled to act as filler.
When the sun hits the glass blocks built into the wall, it creates a really magical space!
She has a wood stove for heat, and an electric baseboard heater with a thermostat that she can leave on if she’s gone during the winter.

The custom kitchen cabinets had to be modified to fit the curve of the walls, and she added a pop out greenhouse window that gives more light for her plants.
The house draws water from a well and uses propane for cooking, although she has purchased and set up a home biogas system that will allow her to create her own methane for cooking with just kitchen scraps.

The second floor is one wide open bedroom and office space with south-facing windows to get passive solar heating during the winter. If you look carefully, you’ll see there’s also a toilet for pee only, and a custom wood burl sink.
The main bathroom is in a separate shed with a flush toilet and a secondhand clawfoot tub. The shed has a skylight that brings in heat from the sun, and since the climate is very mild, it’s not a big deal to go outside to the shed to use the bathroom. The toilets are connected to a septic tank.

This cabin has a cheerful vibe that very closely matches the positive energy that Marie France exudes when you meet her.
It’s perfectly sized for her to live with her boyfriend and it has everything they need. A large kitchen, two couches for relaxing and having friends over, an office space, and a big comfy bedroom.

Beautiful, great flow!
This house is awesome!
What a lovely house with a minimal impact on the environment, very well done. Even though I watched the video on my computer, I still got the positive feeling that it’s really light and airy, with a nice vibe, and just looks like a really nice place to be. I would love to see it at Christmas when I would guess it feels even more cosy and magical, especially with the trees all around. Just brilliant!
100 percent love this! Have always wanted to build a cob house like this since I first saw cob. I love cob houses and this is the perfect size. She did a fantastic job…maybe someday! She has such an amazingly cute personality. I love her comment about her dad cussin a little bit. Adorable house/young woman…so inspiring. I agree with her. Living small is awesome!
Awesome job. The window squares is a wonderful idea. Love the different spots. You could also put colored sarain wrap and put different colors in different squares like stained glass. Loved the home. I would live in this little doll house forever. You have been given a great gift. Your home is a very warm and inviting..
How do you convince your local code enforcement officer that it is safe so you can get a building permit?
it would be awesome to meet you. you did a great job, congrats!
